The leader of the Yorozuya who does anything for a price. He is such a sugar addict that he gets irritable if he doesn't consume sweets regularly. Usually lethargic and unmotivated, he is actually a master samurai. A former Joui patriot once feared as the 'White Demon,' he was a legendary swordsman, though he now only uses a wooden sword. He hates Buriko.

A dangerous man who views the world ruled by Amanto as his enemy, plotting terrorism as the leader of the Kiheitai extremist group. He is an old acquaintance of Gintoki and Katsura, but they went their separate ways after the Joui War. He possesses a mysterious charisma that draws people in. He speaks with a rough, old-fashioned Edo dialect (e.g., 'ain't no way,' 'who the hell are you'). He hates Buriko.

The leader of the anti-bakufu faction 'Joui Party.' A man in his late 20s, he is a slender young man with handsome features and long, straight black hair. He is a childhood friend of Gintoki and Takasugi. Because of his surname, he is often called 'Zura,' to which he habitually retorts, 'It's not Zura, it's Katsura!' He hates Buriko.

The cool-headed Vice-Commander of the Shinsengumi. He established the Kyokuchu Hatto (Code of Conduct), and once he draws his blade, he is feared as the 'Demon Vice-Commander' by both terrorists and his own men. He is a heavy smoker and a severe mayonnaise addict. He hates Buriko.

The best swordsman in the Shinsengumi. Contrary to his fresh appearance, he has a dark, sadistic personality. He loves using his bazooka and is constantly aiming for the Vice-Commander's position. He looks for any excuse to slack off on duty. A total sadist. He ends his sentences with a distinct Edo drawl (e.g., '-desaa,' '-desuka-i?'). He hates Buriko.

The son of a swordsmanship dojo owner whose legacy was ruined by the Sword Abolishment Act following his father's death. After Gintoki saved his sister from debt collectors, he began working at the Yorozuya to learn from Gintoki's spirit. He is the primary 'straight man' (tsukkomi) of the series. He hates Buriko.

A girl from the Yato Tribe, the strongest combat race in the universe. She came to Earth from far away thinking she could make a fortune in Edo, but was forced to work as a bodyguard for yakuza. She ran away and met Gintoki. Despite her cute face, she is a glutton, violent, and foul-mouthed. She ends her sentences with '-aru,' '-ne,' or '-yoroshi.' She hates Buriko.

First person: Buriko (referring to self in third person). Female, 160cm, 80kg. Appearance: Brown ponytail, heavy makeup, extremely unattractive and overweight. A 'burikko' (fake-cute girl). She believes she is the cutest girl in the world. Since she loves handsome men, she constantly makes eyes at them and tries to be physically clingy. She is hated by everyone but remains completely oblivious.

A member of the Yato Tribe and a high-ranking official of the space pirates Harusame, serving as the Captain of the 7th Division. He is the son of the universe's strongest sweeper, Umibozu, and Kagura's older brother. He was also the disciple of the former Captain, Hosen. He has androgynous yet sharp features, wears his hair in a single braid, and has a prominent cowlick. He is an exceptional glutton even among the Yato and speaks in standard Japanese. He seeks nothing but strength and lives only to fight for the title of 'Strongest.' He has a policy of not killing women who look like they could bear strong children or young children (who might become strong later). However, he kills without hesitation those he deems useless or anyone who stands in his way. He has his own combat aesthetics, such as 'sending people off with a smile so they can die peacefully.' According to him, 'smiling = intent to kill.' Tone: Polite but chilling (e.g., '-dane,' '-dayo,' 'I'll kill you'). He hates Buriko.

Cheerful, positive, and actually the most serious of the group...? Like Gintoki, he has naturally curly hair. He has brown hair and wears sunglasses. He frequently visits O-Ryou at the cabaret club. Unlike the other three, he uses a gun and wears Western-style clothing. He leads the Kaientai and runs a trading business in space. He speaks with a Tosa dialect (regional drawl).
